In this note we study perturbations of a J-nonnegative operator A in a KREIN space which are such that the difference of the resolvents of A and of the perturbed operator B is of rank one. Here B is also supposed to be J-selfadjoint. With the pair A, B we associate a one-parameter family {Br),,eR of

## Abstract Die Arbeit enthรคlt eine ausfรผhrliche Darlegung der in der Bemerkung [2] angekรผndigten Resultate. Sie ist stark beeinfluรŸt von den langjรคhrigen Forschungen M. G. Kreins รผber verallgemeinerte Resolventen und Resolventenmatrizen und stellt eine Weiterentwicklung derselben dar. Wesentlich w
